Airtac LRM Miniature Linear Guide LRM12L1X170S10BHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X170S10BHT is a miniature linear guide on a 12 mm stainless-steel rail with recirculating-ball carriage. It is the small end of the range, for light-duty precision positioning in a tight envelope — compact stages, small pick-and-place heads and inspection fixtures.

About the Airtac LRM Miniature Linear Guide LRM12L1X170S10BHT
LRM12L1X170S10BHT is a complete miniature linear guide: one stainless-steel rail 12 mm wide and 170 mm long, drilled with a 10 mm end-hole offset, carrying a single long recirculating-ball carriage. The long body engages more balls and stretches the bearing span, useful wherever a compact head tends to tip as it travels. The set arrives assembled and pre-greased, ready to bolt down.
The T suffix moves the fixing underneath: the rail bolts from below, so the top face stays clear where a machine frame hides the screw line. Inside the carriage, Japanese-made balls graded ISO 3290 G10 - a ball grade only, not an assembly standard - circulate behind a double-lip seal that scrapes oil and shuts out dust, while an outer cover hides the screw strip and keeps larger debris away. Keep the ambient temperature at or under 80 C, with transients no higher than 100 C. AirTAC publishes no load or moment ratings for LRM, so we confirm the capacity for this exact model when you send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L1X170S10BHT Is Used
Benchtop dispensing slide
A fluid-dispensing head crossing a PCB in short strokes: the bottom-mount rail fixes from beneath the deck, leaving the working surface unobstructed.
Fiber-optic alignment fixture
Positioning ferrules under magnification, where the long carriage steadies a small alignment stage against tipping and the H grade keeps travel consistent.
Compact pick-and-place head
Guiding a lightweight suction head over a feeder strip; the stainless rail and sealed carriage cope with the frequent wipe-downs of an electronics bench.
Is the Airtac LRM Miniature Linear Guide LRM12L1X170S10BHT the Right Guide?
LRM is the light-duty end of the miniature range, so match it to small, well-supported loads. If your load is substantial or hangs off a cantilever, go up to LSH: that series publishes per-carriage dynamic, static and moment ratings you can size against, which LRM does not. For very short travel where crossed-roller rigidity beats ball smoothness, LGC is the cross-over choice. Checklist before you order: complete set (not carriage only), 12 mm rail, long carriage, one carriage, 170 mm rail length, preload B - light, so it runs easily but is a touch less stiff than C - accuracy H, bottom-mount fixing, a confirmed load rating from us, and the pairing code if you ever need a lone replacement block. Note that we hold almost no carriage-only stock, so spares are usually a special order.
Quick checklist
- ✓ Complete set, carriage only, or rail only?
- ✓ Load and moment confirmed with us
- ✓ Travel length and mounting space
- ✓ Accuracy grade and preload
- ✓ Mounting surface ground or finish-milled
- ✓ Pairing code, if replacing a part
Installation & Maintenance Notes
- check Mounting surface must be ground or finish-milled.
- check Torque the rail screws per the recommended figures, in sequence.
- check Keep the mounting corner radius inside the stated R maximum.
- check Do not angle the carriage onto the rail; balls can drop out.
- check Drive the supplied bolt caps into the mounting holes.
- check Re-grease every 100 km of travel or every 3–6 months.
- check Installation by qualified personnel per AirTAC docs.
Airtac LRM Miniature Linear Guide LRM12L1X170S10BHT FAQ
Rail width 12 mm, rail length 170 mm with a 10 mm end offset, one long carriage, preload B (light), accuracy H (high), bottom-mount rail fixing. Fixing torque: M3 screws 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium; M2 screws 58.8, 39.2 and 29.4 N.cm respectively. Ambient temperature limit 80 C, transients to 100 C. Re-grease every 100 km of travel or every 3 to 6 months - at a 200 mm stroke cycling once a second, 100 km arrives in about three weeks of continuous running. Basic dynamic load, static load and moment ratings are not published for LRM; we confirm them for this exact model before ordering.
Choose LRM when the envelope is tight and the duty light. Choose LSH when the load is heavy or overhung: LSH publishes per-carriage dynamic, static and moment ratings you can calculate against, while LRM's capacity is confirmed per model through us. The two series have different rail profiles and their parts do not interchange.
